Detailed Description
Embodiments of the present invention will be described below with reference to the drawings.
1. Equipment mounting system
Fig. 1 shows an equipment installation system according to an embodiment of the present invention.
The device mounting system 1 has a first electronic device 10 and a second electronic device 20. The first electronic device 10 and the second electronic device 20 are, for example, image forming apparatuses (e.g., MFPs (multi function Peripheral)).
The first electronic device 10 is an old device to be replaced (replaced), and the second electronic device 20 is a new device to be carried into the installation site of the first electronic device 10.
The first electronic device 10 has a predetermined application installed on a platform such as an operating system.
For example, the application is allowed to be installed only in one device between the provider of the application (the seller of the license of the application, etc.) and the user (the user of the first electronic device 10 and the second electronic device 20). In this embodiment, the user activates (activate) the application by using an activation key provided by the provider to ensure that the application is installed in only one device.
Although the embodiments of the activation key are considered to be various, in the present embodiment, a character string is generated based on an electronic device identifier (serial number) unique to one electronic device permitted by the license and an application identifier (serial number) defined by the application.
However, it takes time for the user to apply for the release of the activation key, and it also takes time until the activation key is released. The issuing source may not be able to promptly cope with the case where the activation key is issued by a sudden replacement (replacement).
Previously, when changing electronic devices, an application was applied to an issuing source of an activation key for issuing the activation key. However, this embodiment is not applied for. In the present embodiment, the first electronic device 10 provides the package file P activating the application installed in the second electronic device 20, so that the user can continue to use the application in the electronic device without interruption during replacement. On the other hand, unauthorized use of the application in the first electronic device 10 is prevented.
The method for moving the package file P from the first electronic device 10 to the second electronic device 20 is not limited, and in this embodiment, for example, the service person goes to the installation location of the first electronic device 10 at the customer, operates the first electronic device 10, and outputs the package file P to the recording medium 40 such as a USB (Universal Serial Bus) memory. Then, the service person causes the recording medium 40 to be read out to the second electronic device 20 located at the service center or the like, and inputs the package file P.
The movement of the package file P may be performed online via a network, and this type of device installation system will be described in a modification of the present embodiment.
2. Hardware configuration of electronic device
Fig. 2 shows a hardware configuration of the first electronic device.
The first electronic device 10 includes a control circuit 11. The control circuit 11 is configured by a CPU (central processing Unit) 11a as a processor, a RAM (Random Access Memory) 11b, a ROM (Read Only Memory) 11c as a Memory, a dedicated hardware circuit, and the like, and is responsible for overall operation control of the first electronic device 10. The CPU11a loads and executes an information processing program stored in the ROM11c into the RAM11 b. The ROM11c fixedly stores programs and data and the like executed by the CPU11 a. The ROM11c is an example of a non-transitory computer-readable recording medium.
The control circuit 11 is connected to a large-capacity nonvolatile storage device 18 such as an image reading Unit 12 (image scanner), an image Processing Unit 14 (including a GPU (Graphics Processing Unit)), an image memory 15, an image forming Unit 16 (printer), an operation Unit 17 (touch panel) including a display Unit 17a, a HDD (Hard Disk Drive) or SSD (Solid State Drive), a facsimile communication Unit 19, and a network communication interface 13. The control circuit 11 controls the operation of the connected units and transmits and receives signals and data to and from the connected units. The operation unit 17 (touch panel) is an embodiment of an input device, and an audio input device including a microphone (microphone) may be provided as the input device.
Fig. 3 shows a hardware configuration of the second electronic device.
The second electronic device 20 is also a hardware configuration similar to that of the first electronic device 10. The second electronic device 20 includes a control circuit 21 in the same manner as the first electronic device 10. The control circuit 21 is configured by a CPU21a as a processor, a RAM21b, a ROM21c as a memory, a dedicated hardware circuit, and the like, and is responsible for overall operation control of the second electronic device 20. The CPU21a loads and executes an information processing program stored in the ROM21c into the RAM21 b. The ROM21c fixedly stores programs and data and the like executed by the CPU21 a. The ROM21c is an example of a non-transitory computer-readable recording medium.
The control circuit 21 is connected to an image reading unit 22 (image scanner), an image processing unit 24 (including GPU), an image memory 25, an image forming unit 26 (printer), an operation unit 27 (touch panel) including a display unit 27a, a large-capacity nonvolatile storage device 28 such as HDD or SSD, a facsimile communication unit 29, and a network communication interface 23. The control circuit 21 controls the operation of the connected units, and transmits and receives signals and data to and from the connected units. The operation unit 27 (touch panel) is an embodiment of an input device, and an audio input device including a microphone may be provided as the input device.
3. Functional construction of electronic device
Fig. 4 shows a functional configuration of the first electronic device.
In the control circuit 11 of the first electronic device 10, the CPU11a operates as the input unit 101, the control unit 102, and the output unit 103 by loading and executing an information processing program stored in the ROM11c into the RAM11 b.
The input unit 101 inputs the derivation instruction, the electronic device identifier Q1, the application, and the application identifier to the control unit 102. The electronic device identifier Q1 is a unique (unique) value unique to the second electronic device 20. The application identifier is constituted by, for example, a serial number and contains information that can specify an application.
For example, in the present embodiment, the instruction for derivation is input by a service person using the operation unit 17.
For example, in the present embodiment, the electronic device identifier Q1 is input by a service person through operation using the operation unit 17. The input unit 101 may download the electronic device identifier Q1 from a server device on a network, not shown, and input the electronic device identifier Q1 to the control unit 102.
For example, in the present embodiment, the application and application identifier is an application and application identifier that is read out from the storage device 18 by the control circuit 11 and input to the control unit 102.
When the export instruction is input, the control unit 102 generates the package file P based on the application, the application identifier, and the electronic device identifier Q1.
The output section 103 writes out the package file P to the recording medium 40.
Fig. 5 shows a functional configuration of the second electronic device.
In the control circuit 21 of the second electronic device 20, the CPU21a operates as the input unit 201 and the control unit 202 by loading and executing an information processing program stored in the ROM21c into the RAM21 b.
The input unit 201 inputs the electronic device identifier Q2 and the package file P to the control unit 202. The electronic device identifier Q2 is a (unique) value unique to the second electronic device 20.
For example, in the present embodiment, the storage device 28 stores the electronic device identifier Q2, and the input unit 201 reads the electronic device identifier Q2 from the storage device 28 and inputs the electronic device identifier Q2 to the control unit 202. The input unit 201 may download the electronic device identifier Q2 from a server device on a network, not shown, and input the electronic device identifier Q2 to the control unit 202.
For example, in the present embodiment, the package file P is recorded on the recording medium 40, and the input unit 201 reads the package file P from the recording medium 40 and inputs the package file P to the control unit 202.
When the package file P is input, the control unit 202 determines whether or not a predetermined condition is satisfied, expands the package file P, and installs an application.
The functional configuration of the electronic device is explained above. Hereinafter, the operation flow of the electronic apparatus will be described.
4. Operation flow of electronic equipment
Fig. 6 shows an operation flow of the first electronic device and the second electronic device.
The control unit 102 of the control circuit 11 determines whether or not the instruction is derived (step S101). For example, when the derivation instruction is input to the control unit 102 through the input unit 101, the control unit 102 determines that the derivation instruction is present (present in step S102). On the other hand, when the instruction for derivation is not input to the control unit 102, it is determined that there is no instruction for derivation (no in step S102).
When the derivation instruction is given, the control unit 102 generates an activation key based on the application identifier and the electronic device identifier Q1 (step S103).
Then, the control section 102 generates the package file P containing the generated activation key, and controls the output section 103 to output the generated package file P to the recording medium 40 (step S104).
For example, in the present embodiment, the input unit 101 inputs the export instruction and the electronic device identifier Q1 based on manual input by the service person, and the output unit 103 writes the package file P into the recording medium 40 such as a USB memory inserted by the service person to output the package file P. In this case, the service person goes to the customer or the like provided with the first electronic device and executes the job.
The package file P is output from the first electronic device 10, moved and input to the second electronic device 20(TR 201). This movement is realized by the recording medium 40 and a service person, for example, but this is only an example.
When the package file P is input through the input section 201 of the control circuit 21 (step S105), the control section 202 decodes and acquires the electronic device identifier Q1 from the activation key within the package file P (step S106).
Then, the control section 202 collates the electronic device identifier Q1 acquired from the package file P with the electronic device identifier Q2 of the own device for collation stored in the storage device 28 of the own device (second electronic device 20) (step S107).
Then, the control section 202 determines whether or not the electronic device identifier Q1 matches the electronic device identifier Q2 (step S108). If the electronic device identifier Q1 does not match the electronic device identifier Q2 (no match in step S108), another package file P needs to be input, and therefore the control section 202 waits until the package file P is input again (return to step S105).
If the electronic device identifier Q1 matches the electronic device identifier Q2 (match in step S108), the control section 202 installs the application so that the function of the application contained in the package file P becomes available (step S109). In addition, the application may be specified by an application identifier contained in the package file P.
Here, the control section 202 installs the application, and activates the application by the acquired activation key. Thereby, after the first electronic device 10 is replaced with the second electronic device 20, the user (operator) of the second electronic device 20 can use the application in the second electronic device 20 immediately, and thus the user can continue to use the application without interruption, so that a so-called downtime does not occur.
For example, in the present embodiment, the service person inserts the recording medium 40 such as a USB memory into the second electronic device 20 placed in a service center or the like to input the package file P.
On the other hand, in the first electronic device 10, the control section 102 of the control circuit 11 newly sets the "replacement transition period" with the output time point of the package file P as the start time point (step S110).
The "replacement transition period" is a period arbitrarily set according to, for example, a period required for mounting the second electronic device 20 and carrying it into the operation destination of the first electronic device 10. For example, a period such as one week is set. The replacement transfer period may be specified by a service person each time, or may be predefined for a number of days and incorporated into the platform or firmware.
As long as during the replacement transition period, the control section 102 does not restrict the use of the application by the user and does not restrict the function even if the package file P or the activation key is output, and therefore the user can freely use the application.
The replacement transfer period can be extended. The input unit 101 inputs an extension instruction to the control unit 102 based on a manual input by a user or a service person using the operation unit 17 or an instruction input via the network communication interface 13.
The control unit 102 determines whether or not an extension instruction has been input to the control unit 102 through the input unit 101 (step S111), and if an extension instruction is given, changes the period component or the predetermined period (for example, one day) component to extend the replacement transition period (step S112).
Then, the control unit 102 determines whether or not the replacement transition period has ended (step S113). After the replacement transition period is completed (step S113 is completed), extension of the replacement transition period is not accepted.
After the replacement transition period has ended (end in step S113), the control unit 102 sets that the application cannot be used (step S114). Here, by disabling, locking, or deactivating (deactivating) the application, it is possible to prevent unauthorized use of the application using the old electronic device.
The service person carries the mounted second electronic device 20 into the installation site of the first electronic device 10 (step S109), and removes the first electronic device 10 therefrom. The new setting of the replacement transition period, the timing of the period, and the deactivation after the end are all information processes executed by the control unit 102 of the first electronic device 10. Therefore, the service person can automatically disable the application without any operation input or the like to the first electronic device 10 which is the old device.
5. Modification example
In the present embodiment, the data structure and format of the information included in the package file P are not limited. However, the control section 102 of the first electronic device 10 may also encrypt the package file P so that the content cannot be changed.
In the present embodiment, the control unit 102 outputs the package file P (step S104), and then newly sets a replacement transition period (step S110). However, the order may be reversed or performed simultaneously.
In the present embodiment, an example in which a service person transfers a package file P (TR201) is illustrated. However, the transmission of the package file P may also be performed not by a human but by a computer system via a network. In this case, the following embodiment can be implemented.
Fig. 7 shows a network configuration of a device installation system according to a modification of the present embodiment.
The device mounting system 1a according to the present modification includes a first electronic device 10, a second electronic device 20, and a server apparatus 30. The first electronic device 10, the second electronic device 20, and the server apparatus 30 are communicably connected to each other via a network N.
The first electronic device 10 and the second electronic device 20 have the same configuration as in the embodiment, and therefore, description thereof is omitted.
Fig. 8 shows a hardware configuration of the server device.
The server device 30 includes a large-capacity nonvolatile storage device 34 such as a CPU31, a ROM32, a RAM33, an HDD, an SSD, or the like, a network communication interface 35, an operation device 36, a display device 37, and a bus 38 connecting these devices to each other.
The CPU31, ROM32, and RAM33 constitute a control circuit 300. The CPU31 loads and executes an information processing program stored in the ROM32 into the RAM 33. The ROM32 fixedly stores programs and data and the like executed by the CPU 31. The ROM32 is an example of a non-transitory computer-readable recording medium.
The control circuit 300 of the server apparatus 30 executes the input of the export instruction to the first electronic device 10, the reception of the output package file P, the input of the received package file P to the second electronic device 20, and the input of the extension instruction to the first electronic device 10 by using such a network configuration and a hardware configuration.
On the other hand, the control section 102 of the first electronic device 10 controls the output section 103 to output (transmit) the package file P containing the activation key to the server apparatus 30. When receiving the instruction to derive and the instruction to extend, which are input from the server device 30 to the first electronic device 10, the input unit 101 inputs these instructions to the control unit 102.
Further, the input section 201 of the second electronic device 20 inputs the package files P to the control section 202 when receiving the package files P from the server apparatus 30.
The control circuit 300 of the server apparatus 30 controls the network communication interface 35 to temporarily store the package file P in the storage 34 and transmit to the second electronic device 20 when receiving the package file P from the first electronic device 10 via the network communication interface 35.
According to the modification described above, the downtime is shortened without depending on the work of the service person.
The configurations disclosed in the present embodiment can be combined and implemented.
6. Conclusion
In general, license transfer must be conducted at the installation site of the electronic apparatus to install a new electronic apparatus. In this case, the time taken for license transfer and installation of a new electronic device is downtime, that is, time during which a user of the electronic device cannot use the electronic device. Installation also includes obtaining an activation key and applying the activation key to the electronic device.
In the replacement of an urgent electronic device, the time from the start of the application for issuance of the activation key to the application of the acquired activation key may be prolonged. In this case, in the method of performing license transfer to a new electronic device at the installation site of the electronic device, there is a possibility that the schedule of the entire replacement work may be lengthened or the work plan may not be made.
(1) In contrast, according to the present embodiment, the electronic device outputs, for export, a package file containing an activation key and an application for making the application available only in another electronic device, and on the other hand, makes the application being used in the electronic device unavailable after a predetermined replacement transfer period has elapsed. Thus, when an electronic device having an application requiring activation of a key in use is replaced, a period during which the application cannot be used in a new electronic device is eliminated, and unauthorized use of the application using an old electronic device is prevented.
(2) According to this embodiment, the electronic device, after outputting the activation key, if it is at a time earlier than the end time of the replacement transition period, if the extension instruction is input, extends the replacement transition period. Thus, even if the transfer job cannot be ended in the replacement transfer period, a period in which the user of the electronic apparatus cannot use the application can be eliminated. Furthermore, according to the present embodiment, the electronic device cannot be extended after the replacement transition period is completed. Thereby, unauthorized use of the application can be prevented.
(3) According to the present embodiment, the electronic device performs input of an export instruction and output of a package file by information communication with a server apparatus on a communication network. Thus, the transfer operation can be performed without manual operation by an operator such as a service person.
While the embodiments and the modifications of the present technology have been described above, the present technology is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the present technology.
